Apache Shiro的身份验证问题

Question

我是Apache Shiro的初学者。我一直在跟踪文档和许多其他教程，博客等，但我就是无法使身份验证工作。当我尝试使用有效的用户名和密码登录时，总是会引发InvalidCredentialsException。我正在使用DynamoDB作为存储用户凭据的自定义领域，但我真的不认为这有什么关系。显然，我存储和/或执行凭据匹配的方式是不正确的。以下是我的设置：

[main]
myRealm = com.enki.closing.users.DynamoDBRealm

credentialsMatcher = org.apache.shiro.authc.credential.Sha256CredentialsMatcher
credentialsMatcher.storedCredentialsHexEncoded = false
credentialsMatcher.hashIterations = 1024

myRealm.credentialsMatcher = $credentialsMatcher

String password = ...
ByteSource passwordSalt = new SecureRandomNumberGenerator().nextBytes();
String hashedPasswordBase64 = new Sha256Hash(password, passwordSalt, 1024).toBase64();

// store the hashedPassword and salt in DynamoDB...
// I've tried storing the salt with and without base64 encoding.

protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
    UsernamePasswordToken userPass = (UsernamePasswordToken) token;
    String username = userPass.getUsername();
    ...
    // pull the matching password and salt out of DynamoDB, no problems...
    ByteSource passwordSalt = ByteSource.Util.bytes( storedPasswordSalt );
    return new SimpleAuthenticationInfo(username, passwordHash, passwordSalt, getName());
}

Answer 1

我想出了怎么让它运转起来。我不得不更改这个（在我的自定义领域impl中）：

ByteSource passwordSalt = ByteSource.Util.bytes( storedPasswordSalt );

对此：

ByteSource passwordSalt = ByteSource.Util.bytes( 
                                  Base64.decode( storedPasswordSalt) );
